Serial No.315,065.

This invention relates to improvements in cloth roll mountings for loomsand it is the general object of the invention to provide for locking themounting positively when the roll is in normal or clothwinding positionin such a way that the cloth roll may be read ily disconnected from itsmounting to permit removal of the cloth.

As the cloth is woven in a loom-it moves forwardly to a cloth roll whichis driven by constantly moving means to wind up the cloth. From time totime it becomes necessary to remove cloth from the loom and to permitthis operation it iscustomary to provide quickly removable mountlngs forthe cloth rolls. The rolls are provided with square openings into whichmay be fitted the squared end of a supporting stud. It 1s an importantobject of my present 1nvent1on to provide a stud which is free to rotatewith the cloth roll and having in saidstud an annular groove to receivea lock which may be removed from the groove to permit endwise movementof the stud in a direction parallel to the cloth roll. 7

In certain devices heretofore used to mount the cloth rolls the lockhasbeen so formed as to be concentric with the roll and when the latterrotates there is a tendency to lift the lock out of locking positionunless the lock is properly lubricated. When the lock becomes disengagedthe cloth roll is likely to fall on the floor and soil the cloth. It isa further object of my PIGSGllb'lIlVEIlflOIl to provide a lock whichmoves about a center eccentric with respect to the axis of the cloth maybe given a plurality of longitudinal positionsto compensate for varyinglengths the cloth roll.

With these and other objects in view which will appear as thedescription proceeds, my invention resides in the combination andarrangement of parts hereinafter described and set forth in the claims.

In the accompanying drawings wherein one form of my invention is shown,

Fig. 1 is a front elevation of the lower portion of a loom having myinvention applied thereto certain parts being shown in section and otherparts being removed for the sake of clearness,

Fig. 2 is a vertical section on line 22 of Fig. 1,

Fig. 3 is atop plan view taken in the directlon of arrow 3, Fig. 2,

Fig. 4 is a Vertical section on line 4-4 of Fig. 2, and

Fig. 5 is an end view looking in the direction ofarrow 5,Fig. 4.

Referring to Fig. 1, the loom frame may be provided with a lower girt 11which sup ports a pair of vertical stands 12 and 13 located respectivelyat the right and left hand sides of the loom. Driving gearing indicatedgenerally at 14 is provided for rotating part of the loom. The righthand end of the cloth roll may be supported on a head 15 non-circular 1ncross section, being suggested herein as square, said head beingassociated with a handle wheel 16 by which the clot-h roll may berotated and being mounted on a stud 17 operatively connected to thegearing 1 1. Said stud extends through a bearing 18 fixed on the rightbracket 12. There is a sliding connection between the head 15 and theinternal bore 19 'ofthe roll C which will'permit the latter to be movedto the left while the head 15 remains at rest. The matter thus fardescribed may be of usual form and of itself forms no part of my presentinvention.

My invention relates to the mounting for the left hand end of the clothroll and in carrying my improvements into eifect I provide the leftstand 13 With'a bearing through which extends astud 81. The latter isfree to rotate in the bearing, although it need not necessarily turn inthe latter during the normal running of the loom. The stud is providedon its left end with an annular groove 32 which lies to the left of thehearing 30.

In order to determine the longitudinal position of the stud 31relatively to the hearing I provide a locking member 33 having arearwardly extending vertical portion 3% proportioned to enter the.groove 32. The rear end of the lock may be weighted as at 35 if desiredwhile the forward end of the lock may have a depending handle portion 36by means of which the lock may be raised. In order to support the member33 1 provide a screw stud 37 which extends through an ear 38 preferablycast integral with the bearing 30. The screw stud is substantiallyparallel to the larger stud 31 and is held in adjusted positionrelatively to the ear 38 by right and left nuts 39 and L0, respectively.A shoulder 41 formed as part of the stud limits movement of the lock 33to the right as viewed in Fig. 1 and a cotter pin 4-2 liniits movementof the lock to the left. It will thus be seen that the screw stud 3Tacting through the lock 33 determines the longitudinal position of themain stud 31. Connection between the supporting stud 31 and the clothroll C is established by a pivoted head which is journaled on a reducedend 51 of the stud 31 and is held between a shoulder 5?. on the stud 31and a washer 53 held in place on the said stud by a screw 54;.

In operation the parts will normally be related as shown in Fig. 1, thegear 1% serving to give a progressive forward movement to the cloth rollC to wind up the cloth as the latter is woven. When it is desired totake a cut of cloth from the roll the handle 36 may be pushed rearwardlyto move the lock about a stud 37 from the full to the dotted lineposition shown in 2. The stud 31 may then be moved to the left away fromthe cloth roll to move the head 50 from the bore 19. The cloth roll Cmay then be moved slightly to the left to disengage the same from thehead 15 after which it may be entirely removed from the loom. lVhen theroll is to be inserted into the loom it will first be fitted over thehead 15 and then the stud 31 will be moved to the right and the head 50inserted into the bore 19. The, looking member 33 will then fall intothe groove 32- to hold the stud 31 against longitudinal movement ineither direction and the cloth roll will be correctly positioned.

I form the head 50 with a flange which may engage the end of the roll Cand said head is perfectly square so as to have proper engagement withthe square bore 19, the form of the head being designated in Fig. 5.

Cloth rolls vary slightly in length and the necessary adjustments may beafforded by means of the stud 3'7. The nuts 39 and 1:0 may be loosenedand the stud turned either toward or away from the cloth roll so as toplace the locking member 33 at ditferent positions relatively to theaxis of the stud 31. The nuts may then be tightened and the lock willserve to hold the stud 31 in proper position.

From the foregoing it will be seen that l have provided a stud which isslidable and also rotatable in a bairing fixed relatively to the loom,the stud being provided with a groove to receive a locking member whichis effective to limit motion of the stud in opposite directions. Byreference to Fig. 2 it will also be seen that the stud 37 is eccentricwith respect to the stud 31 so that any tendency which the stud 31 whenrotating might have to lift the lock 33 will be greatly reduced. I findthat this feature of my invention is of particular value. I find alsothat when removing the cloth roll the lock 33 may be lifted and the stud3'1. moved a slight distance to the left such as will bring that portionof the stud 31 which lies between the groove and the shoulder 52 underthe locking member 33 to support the latter. The operator may thenhandle the cloth roll which will still be supported by heads 15 and 50and move the cloth roll endwise t0 the left because of the fact thatstud 31 is free to slide in the bearing 30.

Having thus described my invention it will be seen that changes andmodifications may be made therein by those skilled in the art withoutdeparting from the spirit and scope of the invention and I do not wishto be limited to the details herein disclosed, but what I claim is:
